Key Differences Between Business Intelligence and Machine Learning
Now that we understand the basic concepts, let’s explore some of the core differences between BI and ML:
Objectives
The main objective of BI is to analyze past and current data to identify trends and patterns that can enhance business operations and decision making. The goal of ML, on the other hand, is to build predictive models that leverage patterns in historical data to drive automated decisions and forecasts about potential future outcomes.
Approach
BI takes a more manual approach, relying on rules and human data analysis to gain insights from structured data sources. ML employs algorithms, statistics and probability to learn from large volumes of structured and unstructured data with minimal human involvement.
Outputs
BI focuses on generating reports, visualizations, dashboards and scorecards to communicate findings to users. ML creates algorithms, predictive models and machine-driven recommendations/outputs.
Data Requirements
BI typically uses structured historical data from databases and internal sources. ML requires large volumes of structured, unstructured and real-time data from multiple internal and external sources for training complex algorithms and models.
Examples
Common BI use cases include sales forecasting, customer analysis and financial reporting. Example ML applications are predictive maintenance, fraud detection, sentiment analysis and product recommendations.
Users
The primary users of BI systems are business analysts, executives and managers interpreting results. Machine learning tools are operated by data scientists, engineers and developers building models.
Tools
Popular BI platforms are Tableau, Power BI, Qlik and MicroStrategy. Common ML frameworks include TensorFlow, PyTorch, scikit-learn, Keras and Apache Spark MLlib.
Additional Considerations
Beyond these core differences, there are some additional factors to keep in mind when comparing BI and ML:
Speed
Once machine learning models have been trained on historical data, they can deliver insights in real-time as new data arrives. This is significantly faster than traditional business intelligence processes which rely on periodic reporting as data is manually analyzed. ML enables organizations to continuously gain insights and make decisions at the speed of business.
Scalability
Machine learning easily scales to analyze massive and diverse datasets with millions or even billions of data points. As data volumes continue growing, ML is better equipped to draw meaningful insights. On the other hand, business intelligence is limited by human analysis capacities and can struggle to glean insights from large and complex datasets.
Complexity
Advanced machine learning algorithms like deep learning are capable of uncovering highly complex patterns and interrelationships in large datasets. They can find insights that would be difficult or impossible for humans to deduce manually. This enables ML to provide a more comprehensive view of phenomena like customer behavior.
Human Oversight
Once properly trained, machine learning models generally operate autonomously with little ongoing human oversight. They continuously analyze new data and refine their outputs. In contrast, business intelligence initiatives require dedicated human analysts to regularly prepare reports and uncover fresh insights.
Costs and Resources
The initial deployment of machine learning solutions demands greater resources for data cleaning, engineering skills, specialized tools and infrastructure. However, these costs can pay off quickly by automating routine tasks and delivering actionable insights at scale. With ML, organizations also need fewer business analysts over time.
Augmenting BI with ML
While distinct, BI and ML can also be complementary and work together seamlessly within organizations. ML can enhance traditional BI systems in powerful ways:
Discover hidden insights
Machine learning algorithms have the unique ability to analyze vast amounts of data and discover intricate patterns that may not be obvious to humans. When applied to the large data warehouses used for business intelligence, ML can uncover deeper insights that were previously hidden. By training algorithms on the historical data stored in a company’s BI system, patterns may emerge that human analysts did not detect through typical reporting and visualization.
For example, an ML model could find that customers who make purchases on a certain day of the week are more likely to complete additional purchases within the next month. Such a subtle trend would be nearly impossible for humans to manually identify but could provide important strategic guidance when uncovered. ML vastly increases the discoverable insights within existing BI data stores.
Improved forecasting accuracy
Traditional forecasting methods in BI often rely on simple statistical projections based on historical patterns. While useful as a starting point, these approaches have limitations and the forecasts may not reflect changing market conditions or disruptions. ML predictive models using the same store of historical BI data as input can generate more accurate forecasts, projections, and simulations of potential scenarios.
By recognizing complex patterns in past sales, customer behavior, product performance and other factors, ML forecasts are able to more precisely predict how those interrelated elements may change and impact the future. This improves planning, resource allocation, budgeting and risk assessment for organizations as they can trust the improved accuracy of ML-driven BI forecasts.
Automated tasks and processes
Routine maintenance and processing of large volumes of BI data can involve much manual effort from analysts and reports authors. Complex generation of period-over-period comparison reports, aggregating metrics from different sources, data preparation for advanced analysis, and other repetitive tasks consume significant resources.
ML automation can help reduce such tasks by programatically completing standard procedures according to predefined models. This frees valuable analyst time to focus on more strategic interpretation of insights, exploration of undiscovered patterns and development of new BI applications and visualizations. Automating mundane aspects of BI management with ML optimization leads to higher productivity.
Real-time decision making
Static reports generated on a schedule are often outdated shortly after delivery, failing to reflect rapid changes in real-world conditions. To facilitate nimble, data-driven decisions, BI must operate in real-time. ML integrated with operational data systems powering dynamic online BI analytics dashboards and interfaces provides up-to-the-minute insights.
Decision makers can take prompt action informed by the latest available information. For example, ML-based recommendations or alerts could guide immediate promotion or repricing decisions based on ongoing sales or inventory levels. Such real-time ML-enhanced BI is increasingly crucial for competitive responsiveness in fast-moving industries.
Enhanced customer understanding
Traditional customer profiling, segmentation, predictive modeling and lifetime value analyses in BI derive highly useful knowledge. However, ML techniques can further refine customer intelligence by detecting minute nuances and change indicators across more diverse data sources.
Combining ML and BI allows a more rounded understanding of individual customers along with high-level segments. Advanced ML algorithms can derive insight from broad datasets encompassing transaction records, website usage, emails, surveys, call center notes and even social media or mobile location data. This drives hyper-personalization helpful for optimizing the customer experience at scale through BI-guided operationalization.
Using AWS for a Seamless BI-ML Integration
Amazon Web Services (AWS) is a leading platform for implementing both BI and ML projects at scale. AWS offers fully-managed services across every layer of data infrastructure including databases, analytics, machine learning, compute, storage and visualization.
Pre-built AWS services like Amazon Redshift, Athens, QuickSight, SageMaker, EMR and Lambda provide a seamless experience for building BI data warehouses, deploying ML models, and operationalizing BI and ML workloads together. Infrastructure automation through AWS Cloud formation also eliminates manual effort.
Overall, AWS simplifies and optimizes the end-to-end workflow from data ingestion and storage, to modeling, deployment and consumption of real-time BI and ML insights across the organization on any device.
